7 Claims.

two frames of the screen together.

The'object of the invention is to provide a clip of the character described which will adjust itself to any warped conditions of the frame so as to obviate binding as the frame members are adjusted to increase or diminish the length of the screen.

A further object of the invention is to provide a clip for slidably connecting the frame members of an adjustable window screen together which will be simple in construction, economical in manufacture and'eifective in use.

In the accompanying drawing:

Fig. 1 is a side view of one of the clips shown applied to one of the frame members of the screen, this view showing the clip in its normal position.

Fig. 2 is also a side view of one of the clips shown applied to one of the frame members showing the position the clip may assume upon warping of the frame members.

Fig. 3 is a longitudinal section on the line of Fig. 1, but also showing the companion frame member of the one shown in Fig. 1.

Fig. 4 isa vertical section on the line 44 of tion of one of the frame members of the screen, this frame member being shown in side elevation in Figs. 1 and 2 and in section in Figs. 3 and 4. A portion of the other frame member is indicated at 2, this frame member being shown in section in Figs. 3 and 4. These frame members have connected therewith screens 3, a portion of which is shown in Fig. 4. Each of the frame members is provided with a dovetailed groove, the groove in the frame member I being indicated at i and the groove in the frame member 2 being indicated at 5.

por-

These frame members are slidably connected together by clips, one only of which is illustrated in the drawing. Each clip in the present case is formed from a single piece of fiat metal indicated at 5 which is punched to provide on one side thereof a divided cup-shaped anchoring member, indicated in general at I. and on the other side thereof with a divided cup-shaped guide member, indicated in general at 8.

The

member 1 comprises flaring wings 1, the outer edge of each of which is formed on the arc of a circle by reason of the cup-shape of this member, and these wings are ofsuch size that when the clip is inserted in the frame member I the wings 5 will frictionally engage the walls of the dovetailed groove 4 and slightly penetrate the walls.

The member 8 also comprises flaring wings 8, the outer edge of each of which is formed on the arc of a circle by reason of the cup shape of 10 this member, the combined dimension of these wings being somewhat less than the width of the dovetailed groove 5 of the frame member 2 in which groove they are designed to freely slide.

It has been stated that the wings I when the clip is driven to position in the groove i l will slightly penetrate and frictionally engage the walls of the groove 4 but by reason of the rounded character of the edges of the wings the clip will be permitted to turn in the groove 4 but at the same time maintain a tight frictional engagement with the walls of the groove 4 to keep the clip v anchored in the groove.

The position assumed by the clip in case the frame members should warp is indicated in Fig. 2 and when such turning movement takes place 'one of the wings 8 of the member 8 will contact the side of the dovetailed groove 5 in the frame member 2 but by reason of the rounded character of this wing it will be permitted to turn in frictional engagement with the wall.

Preferably the inner end of the clip has a. downturned lip 9 which acts as a stop by contacting with the wall of the groove 4.

Having thus described my invention, I claim:

1. In a window screen, relatively slidable frame members each having a dovetailed groove, a clip cooperating with the grooves to hold said frame members slidably together, said clip consisting of a body member, means on one side of said body member to slidably engage one of said grooves and formed to turn therein, and means on the other side of said body member to frictionally engage the walls of the other groove and formed to turn therein, said two means being offset on said body member with relation to each other to permit such turning movement.

2. In a window screen, relatively slidable frame members each having a dovetailed groove, a clip cooperating with the grooves to hold said frame members slidably together, said clip consisting of a plate located between the grooved portions of said frame members, a projection having a rounded edge on one side of said plate to frictionally engage the walls of one groove but permit turning movement of said clip relatively thereto, and

a projection on the opposite side of Said plate slidablymounted in the other groove and turn therein, said projections being offset on said plate with relation to each other to permit such turning movement. 1

- 3. In a window screen, relatively slidable frame members each'having a dovetailed groove, a clip cooperating with the grooves to hold said frame members slidably together, said clip consisting of a plate located between the grooved portions of said frame members, a projection having a rounded edge on one side of said plate to frictionally engage the walls of one groove but permit turning movement 'ofsaid clip relatively thereto, and a projection on the oppsite side of said plate slidably mounted in the other groove, said last-mentioned projection also having a rounded edge ,to permit turning movement thereof in said groove, said projections being located on said plateiin offset relation with each other.

- ,4. In a Window screen, relatively slidable frame members each having a dovetailed groove, a clip cooperating with the grooves to holdsaid frame members slidably together,- said clip consisting ,of a ,plate located between the grooved portions of said frame members, a projection having a rounded edge on one side of said plate'to frictionally engage the walls of one groove but permit turning movement of said clip relatively thereto, a projection on the opposite side of said plate slidably mounted in the other groove formed to permit turning movement thereof in its groove,

said projections being located on said plate in offset relation with each other,,and means to limit the turning movement of said clip.

'5. In a window screen, relatively slidable frame members, each having a dovetailed groove, a clip 7 cooperating with the grooves to hold said frame members slidably together, said clip consisting of a plate located between'the grooved portions of relation with each other, and a projection on one end of said plate to limit the turning movement of said clip; r

6. In a window screen, relatively slidable frame members each having a dovetailed groove, a clip cooperating with the grooves to hold said frame a plate located between the grooved portions of said frame members, a projectionhaving a rounded edge on one side of said plate to frictionally engage the walls of one groove but permit turning movement of said clip relatively thereto, and

a projection on the opposite side of said plate slidably mounted in the other groove also constructed to permit turningmovementof the clip,

members slidably together, said clip consisting of i one of said projections being located near one end of saidplate and the other projection located near the other endcf'said plate. V

v 7. A one-piece clip for relatively slidable frame members, each having a dovetailed groove, said clip consisting of a substantially flat plate, a pro jectio'n formed thereon having rounded V edges,

and another projection formed on a diiferent part and opposite side of said plate also having rounded edges, said projections being formed to permit turning movement thereof in their respective grooves. V
